how did the roosevelt corollary to the monroe doctrine affect the role of the united states in the world??

best answer
This so-called Roosevelt Corollary—a corollary is an extension of a previous idea—to the Monroe Doctrine contained a great irony. The Monroe Doctrine had been sought to prevent European intervention in the Western Hemisphere but now the Roosevelt Corollary justified American intervention throughout the Western Hemisphere. In 1934 Franklin D. Roosevelt renounced interventionism and established his Good Neighbor policy within the Western Hemisphere.
